Morphological and phonetic study attribution-

Objectives: This research aims to explain the morphological changes that occur in the structure of the word when attributed to it, specifically the defective ones, and analyze these changes in the light of modern phonology. Methods: This study fits the descriptive analytical approach. This is in view of the ancients? treatment of these changes and their explanations to reveal their approach in that, as well as the views of some modernists who agreed or disagreed with the ancients. Results: The research concluded that the phonemic factor is the cause of changes in the structure of the word when attributed to it, so it comes to adopt an acceptable syllable, or to modify an objectionable syllable, or to get rid of dynamic duplication, or succession of proverbs, by deletion or shortening, or adding a functional sound that performs a task Construction and separation to solve the phonemic problem in the clip, which is(W) conclusions: The phonetic factor stands behind the changes that occur in the structure of the word when attributed to it, represented by the integrity of the syllabic structure, consistency and phoneme, while ensuring the security of confusion.
